Using the hardware with a current kernel

The current 2.6.23 kernel does not know the CS5530 interrupt router. So it is impossible to let the kernel itself setup PCI's interrupt routing. Even if you provide the kernel with a valid interrupt routing table (PIRQ). No interrupts will work as the interrupt routing registers are still left at their reset values.
The small patch below solves this issue (it was rejected in mainline as it breaks various standard BIOS based Geode systems, as they were shipped with broken PIRQ tables [1]).
